| Self-consumed by your home | 35% (1,361 kWh) |
| Exported to grid | 2,528 kWh |
| Annual electricity bill savings (Assumed 35c/kWh import) | €476 |
| Annual export income | €493 |
| Total estimated 25-year savings | €22,625 |
PV Panels vs Solar Panels
Understand the differences and discover which type of PV panel is right for you.
PV Panels vs Solar Panels - What's the Difference?
People often ask about PV panels vs solar panels. In reality, PV (photovoltaic) panels are a type of solar panel specifically designed to generate electricity. Solar thermal panels, on the other hand, heat water directly. When people refer to "solar PV panels", they mean panels that convert sunlight into electricity.
At LVP Renewables, we help you choose the best solar Photovoltaic panels in Ireland to reduce energy costs and improve energy independence.
Types of Solar Photovoltaic Panel
Roof-mounted PV
The most common choice for Irish homes. Use available roof area to generate electricity where it is produced and consumed.
Balcony & wall-mounted
A compact route to solar for apartments, extensions and homes where a traditional roof installation is not practical.
PV with battery storage
Pair panels with a battery to keep more of your generated electricity available when the sun is not shining.
How do photovoltaic panels work?
Photovoltaic cells turn daylight into electricity through a simple chain of energy conversion. No fuel is burned and there are no moving parts inside the panels.
Sunlight reaches the cells
Daylight lands on the photovoltaic cells inside each panel. The cells are made from a semiconductor, usually silicon.
The cells create DC power
Light energy makes electrons move inside the cells, producing direct current (DC) electricity.
The inverter makes it usable
An inverter converts DC electricity into alternating current (AC), the type your home appliances use.
Your home uses the energy
Your appliances use the solar electricity first. Extra power can charge a battery or flow to the grid.
Components of a solar PV system
A complete system is more than the panels on your roof. These components work together to generate, convert, store and manage your home's electricity.
Photovoltaic cells & panels
The panels capture daylight and generate DC electricity. More efficient cells can produce more power from the same roof space.
Solar inverter
The inverter changes DC power into safe AC electricity and monitors how your system is performing.
Battery storage
A battery stores extra daytime generation so you can use more of your own solar after sunset.
Mounting & cabling
Rails, brackets and cables secure the panels to your roof and connect each part of the system.
Metering & monitoring
Smart meters and monitoring tools show how much energy you generate, use, store and export.
Your home & the grid
Your home receives solar power first. Surplus electricity can be exported to the grid when eligible.
PV Panels with Battery
Storage
Combining solar photovoltaic panels with battery storage helps you get more from your solar energy system. Excess electricity generated during the day can be stored in a home battery and used in the evening or at night.
A 5kWh or larger home battery can help increase your solar energy usage, reduce your reliance on grid electricity and improve the overall efficiency of your PV system. Eligible homeowners may also qualify for the €600 Battery Energy Storage System Grant.
With solar panels and battery storage, you can use more clean energy generated at home and potentially reduce your household electricity costs.
Learn About Battery StorageBenefits of Battery Storage
- Store excess solar energy for evening and nighttime use
- Increase self-consumption from 30% to over 70%
- Backup power during electricity outages
- Use PV panels to heat water via an immersion diverter
- Faster PV panel payback period with maximised savings
SEAI Grants for PV Panels in Ireland
Take advantage of government grants to reduce the cost of your PV panel installation.
SEAI Grant for PV Panels
The SEAI grant for PV panels can help eligible Irish homeowners reduce the cost of installing a solar PV system. The grant may provide financial support towards the purchase and installation of solar panels, with the available amount depending on the current SEAI terms and your property’s eligibility.
Other funding options may also be available for specific properties, including agricultural buildings and energy-efficiency projects. Our team can explain the application requirements, help you understand the potential grant contribution, and guide you through the process from system design to installation.
As SEAI grant amounts and eligibility criteria can change, it is important to check the latest official requirements before starting your project.

Common Questions About PV Panels
What are solar Photovoltaic Panels and how do they work?
Solar PV (photovoltaic) panels convert sunlight directly into electricity using silicon cells, rather than heating water like solar thermal panels do. The electricity generated can power your appliances, charge an EV, or be stored in a battery, with any unused power exported back to the grid.
Are there grants available when I buy solar PV panels in Ireland?
Yes. The SEAI grant for domestic rooftop solar will remain at €1,800 for 2026, and a 0% VAT rate applies to the supply and installation of solar panels on private residences, which adds further savings on top of the grant. To qualify, your installer must be SEAI-registered and the property must have been built and occupied before 2021.
Do solar PV panels work in Ireland's cloudy climate?
Yes. Solar panels generate electricity from daylight rather than direct sunshine, and still produce 20 to 40% of full output on a cloudy day, so they remain effective and cost-efficient across Ireland's weather, not just in summer.
Can I sell excess electricity from my solar PV panels?
Yes. Any electricity your panels generate but don't use is automatically exported to the grid, and you're paid for it through the Micro-generation Support Scheme (also known as the Clean Export Guarantee). This adds to your annual savings on top of reduced electricity bills.
Is it worth buying solar PV panels in Ireland right now?
With the SEAI grant confirmed at Up to €1,800 for 2026, 0% VAT on installation, and rising electricity prices, most systems pay for themselves within 5 to 8 years and continue generating savings for 20+ years after that. Combined with rising property values from an improved BER rating, it remains a strong long-term investment.
How many solar PV panels do I need for my home?
This depends on your roof space, electricity usage, and budget, but most 3-bed semi-detached homes in Ireland install around 10 panels (roughly 4.4 kWp), which also maximises the SEAI grant. Larger or higher-usage households may need 12 to 16 panels for the best long-term savings.
Can solar PV panels heat my hot water?
Yes. An immersion diverter can use surplus solar electricity to heat the water in your hot water cylinder. This allows you to use more of the electricity generated by your PV system and reduce the amount of electricity required for water heating.
